Technical discussion: A week of big weather changes!

A few heavy downpours developed today and a few Urban and Small Stream Flood Advisories were issued. The showers moved very slowly since steering currents aloft are rather week. The threat for severe weather as we head into this evening is very low and any lingering showers will dissipate with the setting sun. The rest of the night will be partly cloudy and mild with patch fog developing. Overnight lows will range from the upper 50s to the mid 60s.

Tomorrow will be partly sunny and warm with moderate humidity. It'll be a little warmer than today with highs in the mid to possibly upper 80s. Once again, there will be a few random showers and thunderstorms in the afternoon and evening that could produce some locally heavy downpours.

Thunderstorms are more likely on Wednesday as a cold front passes through Southern New England. There is the potential for strong to severe storms and the main concern may be large hail and heavy downpours. The atmosphere will be more unstable on Wednesday with colder air moving in aloft. Temperatures will reach the 80s before the cold front moves through.

The end of the workweek looks very nice! Cooler and much drier air will move in on the heels of the cold front for Thursday and Friday. The mercury will dip into the 50s and lower 60s at night. Daytime highs will be in the upper 70s and lower 80s. Very comfortable! The weekend looks great too, although temperatures will be on the rise. Highs on Saturday will be in the low to mid 80s. Highs on Sunday will be in the mid to possibly upper 80s. Both days will feature partly to mostly sunny skies. Temperatures will continue to rise early next week.

Hurricane Bertha is a storm we continue to watch. However, Bertha will likely pass several hundred miles to the south and east of Nantucket late Tuesday night and Wednesday. The only real concern in Southern New England is for beachgoers along ocean facing beaches. Dangerous rip currents are possible. Please be careful!
